Vapi Voice Track
The best voice-first AI build.
The challenge
Make voice the interface. Build a product with a live Vapi voice flow at its core — agents, voice interfaces, or telephony flows.
This is Vapi's first EU hackathon partnership (~1M developers globally). Every builder gets credits to put a voice agent live during the weekend.
How you win
Is it end-to-end working, and genuinely AI-native rather than a wrapper? Plus the quality of the voice-first experience — latency and naturalness.
A real market, a clear wedge, and a path to revenue — a realistic voice-AI business.
Who's the first paying customer, by name? A clear first user for the voice use case.
The Friday-to-Sunday delta — the depth of the Vapi voice flow you actually shipped.
Why this team, why now — and a non-obvious, creative use of voice.
Bonus (no weight): "Would you take a meeting?" — a yes/no gut-check from the judges.
How to stand out
- Put a real, working Vapi voice flow at the heart of the demo — not a bolt-on.
- Pick a use case where voice is genuinely the right interface, and make the conversation feel effortless.
Voice Agents of the Future

A Vapi voice flow live in your demo.
You win
